“…Therefore, sugarcane growers on loam and clay soils are likely to dismiss nematodes as pests due to the apparent health of the crop, whereas subtle but significant yield losses could be occurring. Also, it is difficult to obtain responses from nematicides because they tend to be adsorbed onto clay particles and organic matter (Abdellatif et al 1967;Awad et al 1984). Thus, nematode problems may be more widespread than has been thought in the past.…”

Summary. Five plant–parasitic nematode species were found to be widespread on sugarcane crops surveyed in south Queensland, namely Pratylenchus zeae, Meloidogyne javanica, Paratrichodorus minor, Helicotylenchus dihystera and Tylenchorhynchus annulatus. Apart from Meloidogyne, high nematode populations were found in most soil types, suggesting more extensive crop losses could be occurring than previously estimated. The most important pests were P. zeae and M. javanica, as they were often found at high densities and their pathogenicity on sugarcane is established. Mean densities for most nematode genera did not differ significantly between sugarcane cultivars, except that fewer Pratylenchus were associated with cultivar CP51-21 than other cultivars surveyed. The density of Pratylenchus in roots was significantly higher in plant crops than in ratoon crops, whereas the density of Paratrichodorus was highest in first and second ratoons.

“…Phorate also had a lower against house crickets in sandy soils than in loam soils (Burkhardt and Fairchild 1967). Abdellatif et al (1967) found that aldicarb, a systemic insecticide, produced lower mortalities of aphids feeding on cotton as the soil organic matter content increased. Roberts (1963) tested dieldrin against soil ingesting Cyclocephala larvae (southern masked chafer) and nonsoil ingesting Blissus leucopterus (chinch bug).…”

“…The performance of pesticides depends on many environmental and edaphic factors, including soil type (6), clay arid organic matter content (1), soil water potential (3), pH (10), and temperature (19). Obrigawitch et al (12,13,14), Wilson (18), and others (4,5,7,8,9,10,11,15,17) also reported that repeated applications of the same or similar herbicides decreased their effectiveness by acceler ating microbial degradation.…”

The influence of previous herbicide applications on the degradation rate of butylate [S-ethyl bis (2-methylpropyl)carbamothioate], EPTC (S-ethyl dipropyl carbamothioate), alachlor [2-chloro-N-(2,6-diethyl-phenyl)-N-(methoxymethyl)acetamide], and metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide] was measured. Degradation studies were conducted on soils with zero to eight previous applications of butylate, zero and six consecutive annual applications of alachlor, and zero to seven previous applications of metolachlor. Previous applications of alachlor or of metolachlor did not affect the rate of degradation when the same herbicide was reapplied. Soils with previous butylate-use history had more rapid degradation of butylate or EPTC than soils with no previous butylate applications. Because soil sterilization reduced14CO2evolution to a low level, soil microorganisms could be the primary mechanism of butylate degradation. There was no difference between butylate or EPTC degradation rate in soils treated previously with butylate. Butylate could not be detected 28 days after treatment in soils previously treated with butylate, whereas soils not previously treated with butylate still contained biologically active butylate. Dietholate (O,O-diethylO-phenyl phosphorothioate) added to butylate generally reduced the rate of butylate degradation in soils previously treated with butylate, but the butylate concentration always was lower in soils treated previously with butylate than in soils without previous butylate applications. Weed control in the field showed rapid loss of butylate and EPTC in soils with previous butylate treatment and that dietholate reduced the rate of butylate and EPTC degradation.
