The apprehension among oil palm farmers on the toxicity of glyphosate necessitated the need for an alternative herbicide for weed control in oil palm. Thus, a study was conducted at the Ni­gerian Institute for Oil Palm Research (NIFOR) to determine the efficacy of tank mixture of glu­fosinate ammonium (Basta) + indaziflam (Alion) for weed control in oil palm. The treatments consisted of glyphosate at 1.5 kg a.i ha-1, glyphosate + diuron at 1.5+2.0 kg a.i. ha-1, glufosinate ammonium at 0.4 kg a.i. ha-1, glufosinate ammonium at 0.5 kg a.i. ha-1, tank mixture of glufos­inate ammonium + indaziflam at 0.4 + 0.04 kg a.i. ha-1, tank mixture of glufosinate ammonium + indaziflam at 0.5 + 0.04 kg a.i. ha-1and weedy control. The results showed that tank mixture of glyphosate + diuron at 1.5 + 2 kg a.i ha-1, glufosinate ammonium + indaziflam at 0.4 + 0.04 kg a.i. ha-1 and glufosinate ammonium + indaziflam at 0.5 + 0.04 had the best weed control efficiency of 78.5%, 78.6% and 78.3% respectively up to 20 weeks. The study concluded that tank mixtures of glufosinate ammonium + indaziflam were as good as glyphosate + diuron for weed control in oil palm.

Bullgrass (Paspalum fasciculatum wild.) is one of the most prevalent weeds in the oil palm crop. The objective of the experiment was to compare its control with five herbicides. Three experiments were conducted to evaluate the herbicides haloxyfop-methyl (Galant 240 y Galant 75), fenoxaprop-pmethyl (Excel) and fluazifop-butyl (Fusilade II) at the rates of 50, 75, and 100 g ai/ha-1 and glyphosate (Round up) at the rate of 960 g ai/ha-1 during the first experiment; Galant 240, Galant 75 and Fusilade II at 100 g ai/ha-1 during the second experiment; Galant 240, Fusilade II at the rates of 75 and 100 g ai/ha-1 and glyphosate at 960 g ai/ha-1 during the third trial. A Completely Randomized Block design with four replications was used. Galant 240, Galant 75, and Fusilade II showed the best results as measured by weight of fresh weed, number of affected nodes (herbicide transport), and weed control efficiency percentage. Galant 240 at 100 g ai/ ha-1 was the most profitable option.

Background: Time of pre-emergence herbicide application is an important factor that decides the efficiency of herbicide. If the pre-emergence herbicide is not applied at appropriate time, it may cause ineffective weed control or toxicity to crops. With this background, a field experiment was conducted at TNAU, Madurai to optimize the time of pre-emergence herbicides namely pendimethalin and oxyfluorfen application for effective weed management in irrigated blackgram. Methods: The experiment was laid out in randomized block design with three replication. Treatments were application of pendimethalin at 0.75 kg ha-1 and oxyfluorfen at 0.2 kg ha-1 on 1, 2, 3, 4 days after sowing, weed free check and unweeded check. Result: Results of the study revealed that oxyfluorfen gave maximum weed control efficiency as compared to pendimethalin, but toxicity to the crop was observed when oxyfluorfen was sprayed after 2 days of sowing. Yield and economics were achieved higher with application of 0.75 kg ha-1 of pendimethalin at 2 DAS, which was on par with application of 0.2 kg ha-1 of oxyfluorfen at 1 DAS due to lesser toxicity. Application of 0.75 kg ha-1 of pendimethalin and 0.2 kg ha-1 of oxyfluorfen didn’t leave any herbicide residue after harvest. Hence, application of 0.75 kg ha-1 of pendimethalin at 2 DAS and 0.2 kg ha-1 of oxyfluorfen at 1 DAS can be recommended for effective weed management in irrigated balckgram.

Hand Weeding

A field experiment was conducted during Kharif seasons of 2014 and 2015 at Udaipur (Rajasthan) to find out the effect of weed management on productivity of clusterbean under varying fertility levels. The results revealed that among various weed management practices, two hand weeding 20 and 40 DAS recorded significantly lower weed dry matter, higher weed control efficiency, higher values of yield attributes, seed, haulm and biological yield during both the years over rest of the treatments except sequential application of pendimethalin fb imazethapyr which was statistically at par. Further, application of Imazethapyr fb hand weeding and pendimethalin fb hand weeding also gave comaparable results with pendimethalin fb imazethapyr in terms of weed control efficiency and yields. Among the fertility levels application 20 Kg N + 40 Kg P2O5 ha-1 significantly increased pods plant-1 (24.04), seeds pod-1, (7.12), test weight ( 25.33 g), seed ( 1035 kg ha-1), haulm (2161 kg ha-1) and biological (3196 kg ha-1 ) yield and harvest index ( 31.98 %) of clusterbean over 10 Kg N + 20 Kg P2O5 ha-1 however, it was found statistically at par with fertility level 30 Kg N + 60 Kg P2O5 ha-1. Therefore, clusterbean should be fertilized with 20 Kg N + 40 Kg P2O5 ha-1 and weeds must be controlled with pendimethalin (PE) fb imazethapyr 0.1 kg ha-1 20 DAS .
